Increased Stroke Burdens Among the Low-Income Young and Middle Aged in Rural China [Clinical Sciences]

Background and Purpose—Although stroke in the young and middle aged accounts for 31% of all strokes in China, the disease burden is unknown. We aimed to determine the secular trends in stroke incidence and the transition of subtypes in rural China over a 24-year period.Methods—In 1992, 14 920 residents were recruited to participate in the Tianjin Brain Study. Stroke events and all deaths were registered annually. We assessed the trends in incidence of first-ever stroke, including intracerebral hemorrhage and ischemic stroke, among adults aged 35 to 64 years during 1992 to 1999, 2000 to 2007, and 2008 to 2015. The annual proportion of change in stroke incidence was evaluated from 1992 to 2015.Results—The age-standardized incidence of first-ever stroke per 100 000 person-years increased significantly, from 122 in 1992 to 1999, to 215.8 in 2000 to 2007, to 471.8 in 2008 to 2015. The incidence of first-ever stroke increased annually by 11.9% overall (12.4% in men, 9.0% in women, 8.7% for intracerebral hemorrhage, and 10.7% for ischemic stroke; P
